I look at these things as essentially aesthetic preferences. There's certainly cases where a certain medium is the objectively right one for a task, but there's many others where it really just a matter of taste.
Every single piece of art, music, game or any other creative piece, has three things to it. One, the actual artifact itself of the music, the art and the game. Second is who is making it. And the third is how much have they put into it.
This last point I think matters a lot. As producing things gets easier and easier, just because almost all of creative art is a popularity contest, things will move towards who has put in most of their hearts / effort into it.
And that is why still I think we will always remember a desktop game such as Stardew Valley but never a web game, no matter how good it is. I mean Roblox has been around for a while and maybe I can tell you one or two games in their entire history, which I even remember.
The same with movies from Netflix which are becoming this data oriented, aesthetically pleasing, easy to watch things, but none of them are worth remembering. Will Netflix and these platforms keep growing and having more and more users? Sure.
But therein lies the conundrum. We will have a lot of everything. We will own none of it and our lives will grow more and more shallow and meaningless.
Also, there's definitely web games (paperclips, kittens) and art in every media that are memorable and excellent to someone. That's kind of the point that I was making; the medium is part of the message, but many things can be presented in different ways, and mostly this doesn't detract from anyone else.
Fundamentally, I reject your model of art; I personally think the actual artifact should be the most important part. Anything else shouldn't even be considered as far as we're able, even though we are mostly status seeking monkeys who pay very close attention to every other monkey's status so as to increase our status.
That's just an argument about quality though. In the end it's quality that matters more than the amount of effort expended (which isn't something you can easily quantify or confirm). Technology promises to make things easier allowing for quality that wouldn't have been practical otherwise.
Even when the quality is identical there are times when I can appreciate the effort that went into something just because the creator choose to make something in the most inefficient and painful way possible. That's kind of fun in its own way, but it's the exception, not the norm.
As games, music, and other forms of art get easier to produce and distribute thanks to technology we'll have more to choose from. Having choice will always mean you have a lot of sifting through garbage to find things you like, but technology can make that easier too. I'd rather have an overabundance of options than be forced to select from only a few options because creation/distribution is reserved for a select few due to cost/difficultly
